When is the little dipper in the sky

It is a yellow-white supergiant with an apparent magnitude of 2. Polaris is also the 50 th brightest star in the sky, and it is somewhere around 2, brighter than our Sun. In order to find the Little Dipper, you need to firstly find the Big Dipper. Once you have located it, continue the line between Merak and Dubhe upwards, and you will reach the North Star, which is the brightest star of the Little Dipper.

Afterward, it will be easy to spot the entire asterism as it has a unique pattern. The distance from the Big Dipper and the bright star Polaris measures up to almost five times the distance between Merak and Dubhe. These two stars are also known as the Pointers because they point to Polaris's direction, thus to the direction of the North Pole.

The Little Dipper gained its name because of its aspect. The asterism resembles a dipper, the same way the Big Dipper does. When you look at these two, they are the same, but they vary in size considerably, hence their names.

The Little Dipper is part of the constellation of Ursa Major, the 56 th largest constellation in the sky. The constellation of Ursa Major and thus the Little Dipper can be viewed best during June at 9 p. The asterism formed this particular constellation's wings, but they were later clipped to create a new constellation — Ursa Minor. This happened somewhere around B. They taught Thales how to use the stars of the Little Dipper for navigation.

If you ever wanted to judge the quality of your night sky , you need only look to the bowl of the Little Dipper. The four stars that comprise the bowl run in brightness from second to fifth magnitude. The magnitude system has its origins in the classification by brightness of about 1, stars carried out by the Greek astronomer Hipparchus in the second century B.

The average of the 21 brightest stars in the sky is defined as first magnitude, while the faintest stars normally visible to the unaided eye on a clear, dark night are said to be of sixth magnitude. The magnitude scale is logarithmic. So, a difference of one on the magnitude scale corresponds to 2. That is, second-magnitude stars are 2. The brightest star in the Little Dipper's bowl is Kochab, a second-magnitude star with an orange hue. The two other stars that complete the bowl are of fourth and fifth magnitude.

Kochab forms the lower outer bowl and is an orange giant star only slightly fainter than Polaris at an apparent magnitude of 2. The Little Dipper is visible between latitudes 90 and with the best time to observe in the month of June. However, since the stars in the Little Dipper range in brightness from second to fifth magnitude, it may be difficult to see depending on the quality of your night sky. Polaris nearly in line with the North Celestial Pole.

Light pollution in the form of sky glow from urban city centers and surrounding suburbs affects the overall darkness of the sky. With the stars in the bowl being so dim, you will need a darker sky in order to see them.

This would explain why you might not be able to locate the Little Dipper. While you might not be able to see the Little Dipper, you can use the stars from the Big Dipper to locate Polaris. Simply locate the outer two stars in the Big Dipper bowl Merak and Dubhe and draw an imaginary line through both stars, extended outwards until you locate a bright star-forming the end of the Little Dipper handle. The Big and Little Dipper are arranged with their handles pointing in opposite directions, meaning one Dipper is upright while the other is upside down.

Unlike its Big Dipper counterpart, the Little Dipper does not have many nearly deep-sky objects. The grouping of stars we now know as the Little Dipper was first recorded in B. Since that time, it has been used to chart the positions of other star formations and help sailors navigate the seas. Submit a Tip All tip submissions are carefully reviewed before being published.
